NXT-L29 battery issue - Mate 8 Q&A, Help & Troubleshooting

Hello guys,
I would like to share the issue that recently appeared on my mate 8 (NXT-L29). All was perfect, the phone was really what I looked for. But since something like two weeks, it looks like the battery lost autonomy, and I do't know why, when the phone hits the 50% battery left (not 51%, not 49%, 50%), it sudently cuts off and no reboot is possible, the phone (not android, the phone when it is off) displays that it has no battery (0%).. I lose 50% battery in just.. 1 second! It's really annoying, especially as I used to use it quite intensively, to play, listen to music, surf the web.. so I have the unpleasant feeling of still not being able to benefit from half the capacity of my phone, while I know it is a big battery.
I'm really cautious with my phone, I always let it charge to the maximum before unplug it from the charger and I rarely let it go below the 10%..
I specify that my phone is originally the AL10 version of the mate 8, but I have changed it to the L29 version and all was working properely.
Does anyone can help me please?
Thanks in advance, and sorry for my bad english, i'm french

HTC Touch Pro Battery

I have a htc touch pro (sprint) and i love this phone, its amazing i love everything but the battery. It seems to last about 8 hours even when im not using it heavy. Is this normal (i hope not), or just maybe my battery? Any suggestions?
My Fuze lasts about that long in sleep mode too... Not sleep mode all day, I do use it to text and surf the web once in a while.
I think it's normal, but I don't know...
I'm on the Tael Sense ROM

when your done with the phone press the power button to lock the phoen this greatly improves battery life turn off wi-fi turn brightness down to half way and select display timeout to 10 second and display sleep to 30 seconds also dont have alot of programs running it the back ground when your done with them close them report back if it helps also do you have any apps or your e-mail that constantly use data? if so switch ti to update ever 15 minutes or more
do you have new battery.....? i have used one , so i have exact same problem...but i will try with new one...
also battery caalibration can help you..to improve performannce of battery.....
I also have the same problem ,can somebody doin something...
This is not normal, if you are on custom ROMs make sure you have installed a matching rilphone.dll (plenty of info on this via search)
Also battery calibation is a big concern after flashing custom roms, I always make sure my battery is 100% charged before flashing as from experience found calibration goes a bit off if you have battery partly charged between 50% to 100% & can be a pain to correct. Read Energys notes in any of his ROM threads on battery calibration.
Also on custom ROMs hard reseting after initial setup is good practice & recommended by most chefs.
Last option is you need new battery.

This thread is useless if you don't give us any more info. 1. Are you using a stock ROM or a custom one (cdma, since you have Sprint)? 2. What do you mean by '8 hours'? Do you mean that from 9-5, with the phone in standby, it fully drains the battery? Or do you mean 8 hours of uptime (the phone turned on, and using it)? If it's 8 hours of use, that's not terrible, depending on what you're doing. That's a current draw of 168 mA, which is about what I get if I'm listening to music on tcpmp. It's also about the same as having the screen set to 10 (full brightness) and just having it turned on.
If you want actual help for your situation instead of generalities, you need to supply the following info:
ROM
Lockscreen (custom or standard)
Processes running most of the time
Bluetooth on/off a lot of the time?
Wifi on a lot?
3G?
Schedule for syncing email and crap like that
Custom UI?
Do you use the accelerometer a lot?
You may be doing some things that will burn the battery, but there's no way for anyone to know if you don't tell us how you use the device. The easiest thing to do is get tbattery.exe and log your battery usage to find out what is killing it (if it really is burning too fast). There are also other similar apps out there.

serious problem with vibrant

Hi I have bought vibrant from ebay and using it for about week now
and it has serious battery problem
first of all
right now i am using official updated 2.2
but even before updating there was battery problem so it;s not 2.2 for sure
so i downloaded app called battery minder which gives me % and how many minutes left on my phone
so here is the problem comes when i fully charge my phone
no wifi, no blue tooth, no gps, data turned on it shows i have about like 6 hrs
and when i turn my wifi on and when it;s connected it says i have 18 hrs or something
and when i just turn my bluetooth on without wifi it gives me like 1 more hr from 6 hr so about 7 or 8
and when i make my phone to airplane mode it gives me 22 hrs or something
and the minutes showing on there it;s pretty accruate
so is there way to fix it? and even if there is way to fix it airplane mode and 22hrs i think that's way too little
or is that supposed to be
i don;t know how other ppls battery is so that's why i am posting here
please please help me
i love the phone but battery is just not right
and my point of view right now i do not think it;s the battery because when i turn my bluetooth on it gives me more hrs...
so please help me
i think longest i used in one day is like 8-9 hrs
when i didn;t really do anything with my phone...
maybe i played with it for like 1 hr maximum...
that's maximum usually 6 hrs or 5...
please please help
oh and i tried pulling my battery out and everything...
factory reset...
one last question if it is the battery if i change my battery get it from ebay or something which one should i get if i get those cheap ebay batteries will it damage my phone?
please help thank you so much
The battery drain was fixed for the Vibrant a few builds back. It should only be draining when your screen is on and you're actually using the phone. You may be expecting too much out of your phone. Those who report 14+ hours of use usually get that because they barely touch their phones all day or use it mostly for texting which takes very little battery life.
Dont rely on battery apps. Just use and enjoy your phone.. If you need, extra batteries are cheap online.
are those cheap batteries good?
will they damage my phone?
i see on ebay that like 3 batteries are like 10 dollars...
is that trustable?
and also i am not trying to expect too much it;s just that
when i turn my bluetooth on i get more hrs and i don;t know it;s just not right to me
and when i didn't use my phone at all i had like 40% after 12 hrs
when my friend uses iphone 4 and had 86%
is that why android sucks so much?
I have 2 ebay batteries and have had no problems with either.
thanks for that comment
i guess i will order but i still can;t figure out this battery problem..
You can try reflashing your ROM. But I really don't see a problem. Your phone has a super amoled screen which eats tones of battery. Being connected to 3g eats more battery than wifi, etc. You may just be expecting too much out of your phone tbh.
but that same for the iphone
my friend and i had class so oviously we couldn;t really use our phones
and after like 12 hrs later
he had 86%
and i had 40%
since i didn;t turn my screen on that much
that means i didn;t use the super amoled
and we both were using 3g
so atleast it should be somewhere near iphone
You can't make a direct comparison like that. Your phone and your friends phone have different operation systems, different amount of processes running, different hardware, and different batteries. Not to mention different signal strength which also effects battery life.
thank you for reply i understand what you are saying but
i just don't know
if it;s like 20 % difference i get it..
but 40%?
even though it;s different phoen and different system
it;s way too much..
you can compare mac and window with same spec
it;s not going to be that much different
40% shows me there is something wrong..
If that's what you wana believe. Maybe you should get an iPhone then.

Fast battery drain on the Mi5s occurs when the fingerprint reader is active. Disable it by removing any fingerprints registered in the security setup (in other words, don't use your fingerprint reader option) and reboot. You will notice the phone runs much cooler and the battery lasts much much longer. To permanently resolve the issue and regain use of the fingerprint reader, you must root the phone or find some other way of disabling com.qualcomm.qti.biometric.fingerprint.service.
Until about four days ago, I would never consider taking my Mi5s out of the house because it was useless unless I wanted to drag a power bank with me. A comment by someone got me motivated to dig into this issue and I found other people at xiaomi.eu reporting the basics as I've stated above. Yesterday I removed fingerprints, fully charged the phone and today I have 50% battery left and a cool running phone. Normally, it would be less than 20 % after sitting idle overnight. I've asked Xiaomi to consider an app with root permission to fix this. I am not holding my breath.
Im on custom rom everyday i get around 12-15 hours continue backup excessive usage with wifi and gps on. And even vpn is on because im in china so need vpn for google, facebook and youtube.
Look this I havent locked my phone since 2 hours and battery is still 83 %

Im on ViperOS 7.1.2.
Its best with magisk and xposed and even substratum works good.
Daily 13-18hours battery backup.
I have bought my phone two years back on launch Day. So havent changed my battery also.
I wish somebody update ViperOS to latest security patches then it will be more great

Strange battery problem!

Hi everyone!
My wife has a Mate 8 and recently she has a strange problem where her phone turns off or resets. That happens only while she is using it (seeing a whatsapp video or a gallery's photo, or even sending me a telegram. And in most cases battery level was on 90, 80, or even 50% of charge, and after reboot the battery indicates 1%.... later it turns off again (because of 1% battery) and if you turns on again, the battery level is i in 30% now... but instantly passes to 1% and turns off again.
I thought that it can be a battery problem, and a replacement could be ok... But in my country things like batteries or phone replacement parts bought on ebay may take 1-2 months until receive it... Buuuut...... if that weren't the problem?
So I would like a second opinion...
I thought too... if I root the phone and calibrate the battery... could be that a solution?
Or maybe it could be another problem instead battery (like a memory problem)? I ask this because when the phone is charging, there is no problem. And the first time after I disconnected the charger (which casually is a few minutes after I turn on) there is no problem too.
After the last reboot, when I see the battery graphic in Phone Manager, in the hyper-drainage part it says that Chrome app drain 6mAh (while the other apps drain 1mah)... But the other day it shown the same with Facebook app (which I uninstalled after).
She has:
NXT-L09 C605B585(Android 7)
Thanks very much!
PD: and its impossible take it to warranty support, cause she broken the screen last year and I replaced it So warranty is broken.
PD2: sorry for my bad english
I have also had problems with the battery and replaced the old one with a new one. You can find howto-videos on YouTube. Rooting the phone and recalibrate the battery will most likely not work. Your description of the battery's weird behaviour just sounds like it is broken.
yup..look like the problem with your phone battery man..it's time to change a new battery dude..even mine already changed..same as your problem..
i was in the same doubt you have,what if,what if, and tried a lot of different things,none of them worked,the only one option i had left was to change the battery.i did it and now it works better than new.replace the battery and your problem will be gone.i have seen a ton of people with this phone with the same problem,it looks like the first edition of the battery released with the phone had serious issues.mine didnt even got to 4 months old before it got broken.

Can you please share the link from where you bought your original battery
Thanks
Hi.
Finally I bought a new battery and the problem was solved.
In my case, I distrusted a little with the "original batteries" around in the ebay market, so bought a brand that I know that its a good brand and to make sure I will not have problems in the future: Cameron Sino. I recommend it.
Regards!
PS: Thank a lot for the help!

Battery life has been bad for many years now...

Hi,
So, I have been getting really bad battery life for many years now...
Since I got my first OP phone the OP6 I have had this issue.
So first I thought my op6 was faulty, so lately I got myself an op7 pro. But still, on that phone also battery issues.
After that I traded my op7 pro for an s10+, but later I wanted to get back to oneplus so I traded it again for another oneplus 7 pro.
And here I am still with bad battery life.. And with bad battery life I mean like days with 3 hours SOT and like 20% left. To days with 4 hours and like 20%.
But nothing better than that, ofcourse I tried things myself, so I went to oneplus discord server and asked there. Many people tried to help me. We tried custom roms, custom kernels, battery apps like greenify or doze apps. But nothing works, what we did notice tho, that google play services is on the top almost all times. So I tried a day with only whatsapp, but still google play services drain.
If anyone know tips to extend battery life, or setups like XXX Rom or magisk module with XXX kernel. Let me know, anything is possible.
Kind regards,
Crewz
Hey man, I had similar problems with most of my devices, I traded s10+ for op7pro because of that same battery problem. Now it is not as great as other people experience, since I have read that lots of guys go over 9h sot with similar usage as mine... But I am around 6:30 -7:30 sot per 36-48h usage.(on qhd and 90hz)
Since you have tried most of the stuff... I have copluple of suggestions, it looks that problem may be with your network(frequency)/sim or baseband, had on exynos such problem... I would do like whole wipe wit msm tool end downgrade to Android 9, stay day or two and check your battery( you can always upgrade) then try to change an operator if you have other sim, once I had to buy new sim car, because mine was obsolete... See if there are differences without sim card, change sim slot...
One of the last recourses is trying to see if you can install other, change modem/baseband.. I have no idea for op7 pro... Also region settings may have an impact... Eu or non eu rom and so...
One thing that made noticable difference for me is I red somewhere that Hyperion launcher is better for battery and it is... I got better idle with it... Try it.. and best luck

Hey,
So first of all, thank you for the reply and sorry for the late reaction.
I have done a full wipe with MSM before, but I never did go back to Android 9. I need to say tho that I have had bad battery life on that aswell.
It is maybe a good idea to use without sim, but I really need my sim for calls etc. The range is from 4 to 5 bars, so that should be fine I guess.
I am not experienced at all with changing modem / baseband. If anyone here on XDA can help me with that and explain what it actually does, I would appreciate that.
I will give hyperion launcher a go, thanks!
Solution is very simple, do not use warp charge without necessarily exlusions. Use simple charger 2.4 Amper
Just an idea. If this is happening with multiple phones, it might be the quality of signal you're getting from the towers around you. The harder your phone has to work to find signal, the more the battery is going to drain.

Hello. Why you think so? Quick charging just supplies the charging mechanism for the battery with more power, it doesn't change the way the battery itself works or how the power is stored in the cells. It also doesn't change the way the power discharges from the battery.

doesnt make a difference, you can use warp charge without problems. He just gets the bad battery life from his apps, which are syncing all time in the background.

There's a Magisk Module called universal GMS doze. It might help you out with different wakelocks. Also download fk kernel manager he got a couple apps in his battery info area that controls services an wakelocks and also it'll tell idle drain stats. Also in dev options there's a mobile data always on you can unclick that if still nothing helps I'd try turning your mobile data off an see if that's what's draining you
